Specifically, the bearing wire 21 can extend along the length direction of the light-transmitting jacket and be embedded in the sleeve wall of the light-transmitting jacket 20, that is to say, the sleeve wall of the light-transmitting jacket 20 can completely wrap the bearing wire 21, so that the combination of the bearing wire 21 and the light-transmitting jacket 20 is more reliable, the bearing wire cannot be rubbed to fall off in the assembling process, and the strength and other performances of the light-transmitting jacket 20 can be well improved.

In other embodiments, the load-bearing wires 21 may also be attached to the inner wall or the outer wall of the light-transmitting sheath 20; the load-bearing wire 21 can also be spirally wound on the transparent outer sleeve 20, and can also be arranged in other ways capable of enhancing the performance of the transparent outer sleeve 20; in addition, the load-bearing wire 21 may have one, two, or more.

Other technical features are the same as those of the above embodiments and can achieve the same or similar technical effects, and therefore, detailed description thereof is omitted, and specific reference may be made to the description of the above embodiments.

Example four

Fig. 12 is a schematic structural diagram of a lighting device according to a fourth embodiment of the present invention. Referring to fig. 12, on the basis of the above embodiment, the present embodiment provides an illumination device with another structure, and the illumination device of the present embodiment is different from the above embodiment in that:

the light-transmitting envelope 20 includes: a light-permeable flexible sleeve 22 and a light-permeable shaping sleeve 23 sleeved outside the flexible sleeve 22. Wherein, the flexible sleeve 22 is sleeved on the outer side of the flexible LED circuit board assembly 10.

The shaping sleeve 23 is a case that the shape thereof is fixed after the processing, and the shape thereof may not be changed due to bending deformation or the like caused by external force, for example: the shaping sleeve 23 can be processed into a circular ring shape, an elliptical ring shape, an S shape, a spiral shape or the like according to the decoration requirement.

During specific implementation, the flexible LED circuit board assembly 10 sleeved with the flexible sleeve 22 penetrates into the molded molding sleeve 23, and then the light-transmitting structure is arranged outside the molding sleeve 23 as required, for example, the hollow lampshade 31 is sleeved outside the molding sleeve 23.

In the embodiment, the shaping sleeve 23 is arranged, so that the shape of the lighting device can be kept stable, and the lighting device can be suitable for occasions needing the stable shape of the lighting device; in addition, the molding sleeves 23 with different shapes can be arranged, and the molding sleeves 23 with different shapes can be used independently or in combination, so that various types of lighting devices can be obtained to meet different scene requirements and decoration requirements, namely, the lighting device of the embodiment can be used as a household lamp, a commercial lamp and an outdoor lighting.

Other technical features are the same as those of the above embodiments and can bring about the same or similar technical effects, and are not repeated herein, and specific reference may be made to the description of the above embodiments.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
